BACKGROUND: The long-term increase in life expectancy raises the question of whether the increased life expectancy is accompanied by an extension of years without health limitations. The study analyzes how life expectancy without functional and mobility limitations from the ages of 46 and 65 and their proportions of remaining life expectancy have changed since 2008.
METHODS: We analyze data from the German Ageing Survey of the 2008, 2014, and 2020/21 waves. Life expectancy without functional limitations (disability-free life expectancy-DFLE) was calculated using the Sullivan method. Severe functional limitations (using the Global Activity Limitation Indicator-GALI) and mobility limitations (climbing stairs, walking more than 1 km) were examined.
RESULTS: Compression of morbidity in the GALI has been observed in 46- and 65-year-old men since 2014, but not in women of the same age. In terms of mobility, 46- and 65-year-old men show trends towards compression when climbing stairs and 46-year-old men when walking more than 1 km since 2014. The values for women have stagnated for the first two indicators mentioned, but not for 46-year-old women since 2014 when walking more than 1 km.
CONCLUSIONS: Our analyses show different trends in DFLE depending on the indicator, age, and gender and do not allow a clear answer to the question of morbidity compression or expansion. We tend to see morbidity compression in men, whereas trends of stagnation or expansion tend to be seen in women. These results signal challenges in maintaining functional health, especially in women, and point to the need for targeted interventions to improve quality of life and healthy life expectancy.
UNASSIGNED: EINLEITUNG: Der langfristige Anstieg der Lebenserwartung wirft die Frage auf, ob die gewonnene Lebenszeit mit einer Verlängerung der Jahre ohne gesundheitliche Einschränkungen einhergeht. Die Studie untersucht, wie sich die Lebenserwartung ohne funktionelle und Mobilitätseinschränkungen ab dem Alter 46 und 65 Jahre sowie ihre Anteile an der Restlebenserwartung seit 2008 verändert haben.
METHODS: Wir analysieren Daten des Deutschen Alterssurveys der Wellen 2008, 2014 und 2020/2021. Die Lebenserwartung ohne funktionelle Einschränkungen (Disability Free Life Expectancy – DFLE) wurde mit der Sullivan-Methode berechnet. Untersucht wurden starke funktionelle Einschränkungen mit dem „Global Activity Limitation Indicator“ (GALI) und Einschränkungen der Mobilität (Treppensteigen, mehr als 1 km Gehen).
UNASSIGNED: Kompression der Morbidität beim GALI ist bei 46- und 65-jährigen Männern seit 2014 zu beobachten, bei gleichaltrigen Frauen dagegen nicht. Bei der Mobilität zeigen 46- und 65-jährige Männer Tendenzen zur Kompression beim Treppensteigen und 46-jährige Männer beim Gehen von mehr als 1 km seit 2014. Die Werte für Frauen stagnieren für die beiden erstgenannten Indikatoren, aber nicht für 46-jährige Frauen beim Gehen von mehr als 1 km seit 2014.
CONCLUSIONS: Unsere Analysen zeigen je nach Indikator, Alter und Geschlecht unterschiedliche Trends der DFLE und lassen keine eindeutige Antwort auf die Frage nach Morbiditätskompression oder -expansion zu. Kompression der Morbidität sehen wir eher bei Männern, Tendenzen der Stagnation oder Expansion dagegen eher bei Frauen. Diese Resultate signalisieren Herausforderungen in der Erhaltung der funktionellen Gesundheit vor allem bei Frauen und weisen auf die Notwendigkeit gezielter Interventionen hin, um die Lebensqualität und die gesunde Lebenserwartung zu verbessern.

Limitations to usual activities due to health problems impact quality of life and well-being. The Global Activity Limitation Indicator (GALI) was developed to assess the trends in limitations to usual activities. The GALI question is applied in a single or routed, multi-question version. GEDA 2014/2015-EHIS for the first time applied a three-question version. Three quarters of respondents reported that they did not experience any limitations to their usual activities. 18.7% of women and 17.0% of men said they had experienced moderate limitations. 6.4% of women and 6.8% of men reported severe limitations. The share of respondents experiencing limitations increases with age and shows a clear education gradient. Changes in methodology, however, mean that current results based on the GALI question cannot be compared to the results from earlier survey waves of the same study.

The Global Activity Limitation Indicator (GALI) is a single-item measure of functional decline, it is widely used in Europe but it has never been validated in an Asian population. The aim of this study was to validate the GALI in a sample of older Taiwanese people and to explore whether it captured not only physical but also psychological limitations.
Data for 4961 individuals (mean age, 62.4 ± 9.4 years; 47.2% men) were obtained from a national representative refresh cohort of the 8th wave of the Taiwan Longitudinal Survey on Aging. Logistic regression analysis was used to examine associations among the GALI, activities of daily living (ADLs) and instrumental activities of daily living (IADLs) and to explore whether depressive symptoms (measured by the Center for Epidemiologic Studies Depression Scale, CES-D) could be an indicator of reporting limitations on the GALI.
Responding to the GALI, 21.7% of the sample described themselves as \'limited.\' In logistic regression, the GALI response was significantly associated with those who reported one or more ADL difficulties (odds ratio [OR] = 35.89, 95% confidence interval [CI] 21.10, 61.03) and IADL difficulties (OR = 13.37, 95%CI 10.09, 17.71), respectively. Furthermore, those with more depressive symptoms were more likely to report they were \'limited\' on the GALI.
These findings provided evidence that the GALI is a valid tool to assess general limitations in an Asian population. Furthermore, it captured psychological limitations to some extent. There were variations between Taiwan and European countries (as has been previously reported between European countries). The reporting level in the GALI by the Taiwan population was comparatively lower than that in European countries, highlighting the need to embrace cultural differences and to use caution when comparing GALI results across countries.
